Somebody guide me how to make a full backup for phone 4s (5.01 9A406) before I jailbreak it. Make sure when I restore it, the FW will be still the same (5.01 9A406), and the jailbreak have to disappear. Like a new iphone 4s at begining when I bought it. please help me... -----I used "iPhone4,1_5.0.1_9A406_Restore.ipsw" tried to shift-restore in itune, but it said error 3194. I used software such as Tinyumbrella, iSHSH, and delete the host file, but it still the same error 3194. In short: I want to make sure the full backup, after I jailbreak I can still restore like a new iphone 4s (5.01 9A406) I bought. please help me !!!
